Obsolete....
09/01/2019 at 12:44 • 0 commentsAs many people pointed out the TSWB3NCB222LFS from C&K is obsolete.
It's not available anymore, later i have found in Hong Kong a shop but i have discovered that is a scam shop. At this poit, I was thinking that this project is over, once i have finished my stock i should have click the " Retire " button on my Tindie store.
Fortunately with some help, i have found the company Zippy that have the same item!

Small changes in the design
07/04/2019 at 09:39 • 0 commentsI have run a new PCB batch and i have changed a little bit the design.
First of all the PCB have the ENIG finishing.Now the space for soldering the pull-up resistors is gone, instead they are already soldered and can be enabled by shorting a 3-way jumper:
I have also added 2 huge pads for the power supply near the RGB led footprint. In this way is easy to solder some wires for powering something connected to the GP pins.
